This paper reviews the literature on urban sustainability with the objective of drawing more attention to the social aspect of sustainability in urban planning. Given that social capital is a crucial component of moving towards more progressive smart cities and urban innovation, it is important to investigate the social dimension of sustainability and the opportunities that just cities can bring to improve the quality of life for urban dwellers. This paper is divided into three sections. The initial section provides an introduction to urban sustainability, discussing the historical roots of sustainability and sustainable development ideas, the three fundamental elements of sustainability, and the process of defining and measuring sustainability in an urban setting. Moving on to the second section, it delves into the body of work related to linking urban sustainability with urban strategies. The third section finally addresses the emergence of literature on just sustainability and just cities, which can give valuable insights to city policymakers who are trying to improve balanced sustainability.

The performance of smartphone applications are usually constrained in user interactions due to resource limitation and it promises great opportunities to improve the performance by exploring the smartphone built-in and embedded sensing techniques. However, heterogeneity in techniques, semantic gap between sensor data and usable context, and complexity of contextual situations keep the techniques from seamless integration. Relevant studies mainly focus on feasibility demonstration of emerging sensing techniques, which rarely address both general architectures and comprehensive technical solutions. Based on a proposed functional model, this investigation provides a general architecture to deal with the dynamic context for context-aware automation and decision support. In order to take advantage of the built-in sensors to improve the performance of mobile applications, an ontology-based method is employed for context modelling, linguistic variables are used for heterogeneous context presentation, and semantic distance-based rule matching is employed to customise functions to the contextual situations. A case study on mobile application authentication is conducted with smartphone built-in hardware modules. The results demonstrate the feasibility of the proposed solutions and their effectiveness in improving operational efficiency.

The purpose of this study was to analyze the validity of teacher evaluation policy for professional development and to suggest the ways to improve the policy in school. The teacher evaluation policy for professional development is designed to improve teacher professionalism and quality of school education. For this purpose, A survey was conducted and 361 elementary and middle school teachers participated in Busan. Collected data were analyzed using SPSS WIN 12.0. The conclusions of this study are as follows: First, although teachers are highly interested in the teacher evaluation policy, they have negative attitudes for practicing the new policy. Second, assessors must be composed of reliable, competent experts because teacher evaluation has a great influence on teaching activities. The assessors should be composed of those who have the specialization and reliability on the basis. Also the assessors must be trained to enhance the fairness, objectivity and reliability by rigid discipline. Finally, teacher evaluation policy should be closely linked to increasing teacher's expertise such as training opportunities, teacher consultants, and senior teacher systems and should be widely utilized for the evaluation to be effective.

In the rapidly changing information age, as the need for Informatization education increases, it is necessary to further activate Informatization education for adults. First, in terms of lifelong learning, this researcher suggested learner analysis, class subject materialization, and lecture environment confirmation as three things to be considered first before the course is opened. And as a matter to be continuously considered in terms of lifelong learning, this researcher considered that the connection with the next quarter class and the continuity of learning opportunities should be considered. This study attempted to reveal the differentiated characteristics of informatization education in terms of lifelong education by presenting and analyzing three actual class cases taught by this researcher at lifelong education institutions. Its characteristics included customized education in the information age, continuous upgrades of equipment, instructor education in response to the information age, and expansion of employment opportunities. Based on the case of information education classes, this study, which analyzed the differentiated characteristics of information education at the lifelong education level, can help improve the quality of instructors and self-development of learners in the actual educational environment. For this, continuous follow-up research will also be needed.

Objectives: This study aimed to analyze the relation between factors related to the clinical performance competency of dental hygiene students and their clinical learning environment. Methods: The study conducted a survey of dental hygiene students from October 18 to 30, 2023. The data were analyzed using one way analysis of variance, t-test, and stepwise multiple regression. Results: The total practicum lasted ≤10 weeks, 11-15 weeks, and ≥16 weeks for 41.7%, 33.5%, and 24.8% of the students, respectively. Half of them had experience at only one clinical institution. Clinical learning environment had an average score of 3.46 points, whereas the average clinical performance competency of the participants was 3.60 points. The major influencing factors on clinical performance competency were identified as preceptor' s guidance (β=0.277), work participation opportunities (β=0.213), and perceived importance of clinical practice (β=0.136). Conclusions: Efforts are required to provide students with prior education on the importance of clinical practice, improve the clinical learning environment with a focus on preceptor's guidance and work participation opportunities. And standardize various elements to resolve differences in the practice of clinical institutions across regions.

Purpose: This study focuses on the golden banana (Kluai Hom Thong) from the Ban Khok Banana Community Enterprise Group in Sang Khom District, Udon Thani Province, Thailand. Despite its potential as an export crop and minimal disease or insect management issues, the group's products struggled to reach international markets due to lack of marketing opportunities, distribution channels, and proper packaging. The research aims to analyze and develop packaging and logos to test market potential for the group's products. Research design, data and methodology: Data was collected through questionnaires developed in conjunction with three printing and packaging design experts. Market testing involved 100 randomly sampled consumers of the group's products. Results: The new packaging design was perceived as more international, modern, and suitable as a souvenir for adults. Conclusions: Integrating ethnic elements and local materials into packaging design can enhance product appeal. For example, creating cloth bags from fabric scraps for carrying local woven products can impress consumers. This approach could help overcome market barriers and improve prospects for golden banana products in international markets while maintaining the intact ecosystem and environment of the production area. The study highlights the importance of effective packaging and branding in addressing market access challenges for local agricultural enterprises, potentially opening new opportunities for community-based businesses.

This paper analyzes factors affecting corporate investment decisions in economic groups listed on the Vietnam stock market. The panel data of the research sample includes 39 economic groups listed on the Vietnam stock market from 2009 to 2019. The Generalized Least Square (GLS) is employed to address econometric issues and to improve the accuracy of the regression coefficients. In this research, the investment rate is a dependent variable. Cash-flow (CF), Investment opportunities (ROA), Fixed capital intensity (FCI), Leverage (LEV), Sales growth (GR), Size (SZ), Business risk (RISK) are independent variables in the study. The model results show that cash flow and sales growth have the same impact on investment decisions of economic groups in Vietnam. In addition, investment opportunities have a negative impact on the capital investment decisions of economic groups. The remaining factors include fixed capital intensity, leverage, firm size, and business risks that have a weak and insignificant impact on capital investment decisions of economic groups in Vietnam. The findings of this article are useful for business administrators, and helping business managers make the right financial decisions. Besides, the research results are also meaningful to money management agencies. The authors recommend that the State Bank of Vietnam should maintain a sustainable monetary policy.
